In my modest 10 years experience with overhauling engines (both personal and professional) I have only come across 2 examples of being able to just replace a damaged bearing with no additional work and had success. In both cases they had been spun but did not damage the surface of the crankshaft. If you disassemble, check visually for scoring/grooves/discoloration from heat, then check with micrometer for out of round and or plastiguage and find no other issues then bearing can probably be replaced with no additional issues. Like I said though I have only ever seen/done this 2 times with success. Also make sure the locking tabs in the rod and cap are not damaged.
Good Luck
